摘要

本文提出了一种用于模拟乘法器的新型低压拓扑结构。该电路可与单个低功率电源配套使用。完整的电路只有12个晶体管;因此,它满足了模拟VLSI系统中对紧凑子电路的需求。对电路的功耗、总谐波畸变等特性进行了数学分析,并给出了在0.18µm CMOS工艺下的仿真结果。结果显示,在1.2V单电源、1.1%总谐波失真(THD)和1GHz带宽下,功耗为113 μ W。

A 1.2V single supply and low power, CMOS four-quadrant analog multiplier
In this paper, a new low voltage topology for analog multiplier is presented. The circuit can be used with single low-power supply. The complete circuit has only twelve transistors; therefore, it satisfies the need for compact sub-circuit in analog VLSI systems. The mathematical discussion on the power consumption, total harmonic distortion and other features of the circuit and also simulation results in 0.18µm CMOS technology are presented. The results show 113µW power consumption with 1.2V single supply, 1.1% total harmonic distortion (THD) and 1GHz band-width.
